Vishay Intertechnology announced that certain devices in its AC and AC-AT series of cemented, axial-leaded wirewound resistors are now available with a pick-and-place friendly lead-bending option. The WSZ lead form allows the devices to be used as surface-mount components
By offering high-power dissipation and excellent pulse capability, the Vishay Draloric resistors are the industry’s first such devices to be offered in a non-inductive version. The devices available with the WSZ lead form are shown in the table below.
Resistors with the WSZ lead form can be assembled on the PCB alongside other surface-mount components to improve the pick-and-place process and lower costs. The devices will serve as snubber, load, and inrush current limiting resistors for pre-charge/discharge applications in automotive and industrial electronics, energy meters, and white goods power supplies.
For challenging operating conditions, the devices feature a robust, non-flammable silicone cement coating that conforms to UL 94 V-0. The resistors operate over a wide temperature range of -55° to +250° C and offer a wirewound construction that meets the highest requirements against mechanical resistance, thermal shocks, dielectric strength, and insulation resistance at high temperatures.
The RoHS-compliant, halogen-free devices offer tin-plated terminations for compatibility with lead (Pb)-free and lead (Pb)-containing soldering processes.
